- From symmetry, the electric field E at point P (and also the fields E+ and E- due to the separate charges that make up the dipole) must lie along the dipole axis, which we have taken to be a z axis. From the superposition principle for electric fields, the magnitude E of the electric field at P is
- The product qd, which involves the two intrinsic properties q and d of the dipole, is the magnitude p of a vector quantity known as the electric dipole moment, p,of the dipole.
